ABSTRACT:
An antenna (10), illustrated in FIG. 3 , comprises a substrate (11), having an upper surface and and a lower surface, and a transformer (14) having a first conducting track (12) formed on the upper surface and a second conducting track (13), mirroring the first conducting track (12), formed on the lower surface, wherein both first and second conducting tracks have an extremity at opposite ends thereof. The antenna (10) further comprises at least one radiating means, comprising a conducting track on the substrate, and an unbalanced line (20) which provides a first potential (21) and a second potential (22). The first potential (21) and the second potential (22) are coupled centrally (30,31) to said first (12) and second (13) conducting tracks respectively. Furthermore, the at least one radiating means is coupled to one of said extremities.
